Answer:
∠EGB= 68°
Step-by-step explanation:
∠EGB= ∠AGF ( vert. opp. ∠s)
∠EGB= 68°
If 2 straight lines intersect, then the angles facing opposite each other are equal. In this case, the 2 lines are AB and EF.
Answer:
Graph C
Step-by-step explanation:
First we will multiply both sides by 2 to eliminate 1/2 from h.
2 x A = 1/2bh x 2
2A = bh
Now we divide both side by b to eliminate b from h.
2A / b = bh/b
2A/b = h
Answer:
129.9 kPa
Step-by-step explanation:
The relationship between temperature T, volume V and pressure P is given by the ideal gas equation which is given as
K = PV/T where K is a constant such that were there is a change of temperature T₁, volume V₁ and pressure P₁ to temperature T₂, volume V₂ and pressure P₂ then the relationship may be given
P₁V₁/T₁ = P₂V₂/T₂
where T is measured in ⁰K
T₁ = -50 + 273
= 223 ⁰K
T₂ = 102 + 273
= 379 ⁰K
5 × 107/223 = P₂ × 7/379
P₂ = 129.9 kPa
Answer:
(2,4)
Step-by-step explanation:
The formula for a circle is ( x - h )^2 + ( y - k )^2 = r^2
From this formula the center of the circle is always (h,k)
For this question h=2 and k=4 so the center of the circle would be (2,4)
